Helena is the State Capital and the location of Node 128, about 70-80 miles SE of a missile silo. The silos are scattered all over central Montana and are pretty well delineated by the white dots which are potential nuclear targets in a 2,000 warhead scenario. The triangles represent potential nuclear targets in a 500 warhead scenario. (Note: Boise, Idaho has two MADAR Nodes, 111 and 116.)
The AF removed the missiles from some flights in the Malmstrom missile field some time ago. This is mentioned in the Wiki article. I’m not sure but the missile field maps may not reflect the current configuration accurately.
Primary targets, United States
This first map is not representative of the whole missile field and confirms this on the legend. It was drawn for the
book "Faded Giant" and excludes some flights west and NW of the base.
Montana has more than an interesting history tied to the nuclear connection and UAP. Jim Klotz (operator of Node 100 in Moutlake Terrace, Washington) co-wrote the book ("Faded Giant", 2005) with Robert Salas on the Malmstrom incident provided the two detailed missile field maps above. Each missile silo in the 15 some-odd flights of 10 Minuteman missiles were about 2 miles from each other, and each flight had an isolated LCF (Launch Control Facility).
The link below shows the current sighting level as tabulated by NUFORC in Seattle:
Feb. 23, 1967; Glaskow AFB, Montana (BBU)
Two separate groups of two personnel each apparently observed the same unidentified object(s). The same apparent object was observed on a MG-13 Fire Control radar. The length of observation was given as two hours. (Dan Wilson, McDonald list; FUFOR Index)
March 16, 1967; Near Roy (about 30 miles NE of Lewistown), MT (BBU)
8:45 a.m. Echo-Flight of 10 Minuteman nuclear ICBM's of Malmstrom AFB, USAF 341st Strategic Missile Wing, SAC, were inexplicably deactivated within 10 seconds of each other and for 1 day after UFO's hovered near 2 missile silos. Followed a series of UFO sightings during early morning hours by USAF security teams. Similar unexplained deactivation of Minuteman's occurred with O-Flight earlier in the morning. (CUFON; NICAP; not in BB files??)
November 7, 1975; Malmstrom AFB, Montana
Targeting system tampered with.
November 8, 1975; Malmstrom AFB, Montana
F-106's scrambled after UFOs
